VIewInG bluechart G2 InformatIon
BlueChart g2 technology for the coastal United States (including Alaska and Hawaii)
is preloaded on Garmin’s GPSMAP 492 and GPSMAP 498 chartplotters, as well as its
large- display GPSMAP 2200 series and GPSMAP 3200 series of chartplotters.
To access additional BlueChart g2 functionality, you can purchase preprogrammed data cards.
These BlueChart g2 data cards include highly detailed coastal roads and points of interest such
as restaurants, lodging, local attractions, and more. Full-color aerial photos of ports, marinas,
bridges, and navigational landmarks are also included on many data cards. See page 7 for
information on viewing photos while using a preprogrammed data card.
